The Karp class were a class of submarines built by Krupp Germaniawerft for the Imperial Russian Navy. The class, composed of three boats (Karp, Kambala, Karas) were ordered in the 1904 emergency programme as a result of the Russo-Japanese War. The design was a twin hull type powered by a kerosene-electric power plant with a 16-fathom (96 ft; 29 m) diving limit. The boats were delivered late for the war and transferred to the Black Sea Fleet by rail in 1908. In 1909, Kambala was lost. The other two submarines remained in service until their withdrawal in March 1917. They were taken over in April 1918 by the Ukrainian State before being captured by the German Empire in May and transferred to the British following the German surrender in November. The British scuttled Karp and Karas in 1919 to prevent their capture by the Soviets.
